A method and system for aspirating sample volumes from luggage/packages for testing includes a series of rollers that convey each luggage article or package through a pressurized flow of air; the rollers are organized to subject each luggage article or package to a series of forces or kinetic movements to effect a momentary volumetric reduction and/or cause displacement of the contents to cause interior air to be expressed or aspirated. A sensor suite tests the aspirated air for the presence of proscribed materials, including those related to explosive, hazardous chemicals, and/or biohazards.
